Abstract

Abstract A thermosetting and active energy ray curable resin composition is disclosed which contains, as active constituents, a polymer having a (meth)acryl equivalent of 100 to 300 g/eq, a hydroxyl value of 50 to 550 mg KOH/g, an epoxy equivalent of 7000 g/eq or more and a weight-average molecular weight of 5000 to 100000 and a heat-curing agent. A transfer material is also disclosed which includes a protective layer formed of the heat-crosslinking reaction product of the resin composition on a base sheet. A method of producing a molded article includes adhering the transfer material to a molded article or applying the transfer material to the inside of a mold, filling a cavity of the mold with a resin by injection to form a molded article and simultaneously adhere the transfer material on the surface of the molded article, and removing the base sheet and irradiating the surface of the molded article with an active energy ray to form the protective layer.

Independent Claim 56 words
1 . A thermosetting and active energy ray curable resin composition comprising, as active constituents, a polymer having a (meth)acryl equivalent of 100 to 300 g/eq, a hydroxyl value of 50 to 550 mg KOH/g, an epoxy equivalent of 7000 g/eq or more, and a weight-average molecular weight of 5000 to 100000, and a heat-curing agent.
Claim 2
Dependent Claim 56 words
1 . A thermosetting and active energy ray curable resin composition comprising, as active constituents, a polymer having a (meth)acryl equivalent of 100 to 300 g/eq, a hydroxyl value of 50 to 550 mg KOH/g, an epoxy equivalent of 7000 g/eq or more, and a weight-average molecular weight of 5000 to 100000, and a heat-curing agent.
Claim 3
Dependent Claim 36 words
2 . The resin composition according to claim 1 , wherein the polymer is a reaction product of the addition of a monocarboxylic acid having an unsaturated double bond to a polymer having an epoxy group.
Claim 4
Dependent Claim 27 words
3 . The resin composition according to claim 2 , wherein the polymer having an epoxy group is a homopolymer of glycydyl(meth)arcylate or a co-polymer of glycydyl(meth)arcylate.
Claim 5
Dependent Claim 39 words
4 . The resin composition according to claim 1 , wherein the heat-curing agent is one or more compounds selected from the group consisting of chelate compounds, metal alkoxides, silane coupling agents and partial hydrolysate thereof, and acid anhydrides.
Claim 6
Dependent Claim 15 words
5 . The resin composition according to claim 1 , further comprising a photopolymerization initiator.
Claim 7
Dependent Claim 28 words
6 . A transfer material comprising a protective layer formed of a heat-crosslinking reaction product of the resin composition according to claim 1 on a releasable base sheet.
Claim 8
Dependent Claim 25 words
7 . The transfer material according to claim 6 further comprising an image layer and an adhesive layer in this order on the protective layer.
Claim 9
Dependent Claim 58 words
8 . A method of producing a molded article, comprising the steps of: adhering a transfer material according to claim 6 to a surface of a molded article; removing the releasable base sheet; and irradiating the surface of the molded article with an active energy ray, thereby forming a protective layer on the surface of the molded article.
Claim 10
Dependent Claim 88 words
9 . A method of producing a molded article, comprising the steps of: applying a transfer material according to claim 6 to the inside of a mold; filling a cavity of the mold with a resin by injection to thereby form a molded article and adhering the transfer material to a surface of the molded article simultaneously; removing the releasable base sheet; and irradiating the surface of the molded article with an active energy ray to thereby forming a protective layer on the surface of the molded article.
